A mixture of compound D5 (1 g, 4.148 mmol) and phosphorus (V) oxychloride (2 ml) was subjected to microwave heating at 130° C. for 15 min. After cooling to room temperature, the solvent was evaporated in vacuo. The residue was then treated with NaHCO3 (aqueous sat. solution) and extracted with DCM. The organic layer was separated, dried (MgSO4) and evaporated in vacuo. The crude product was purified by column chromatography (silica gel; Et2O as eluent). The desired fractions were collected and evaporated in vacuo to yield compound D6 (0.6 g, 56%) as a yellow solid.
